For launching fiber 300, apply positive voltage to the terminal 302B of optical fiber 300.Control the voltage that imposes on positive terminal 302B by the signal section ground that positive raceway groove (P-ch) field-effect transistor (FET) 802 provides.Activate (that is, " opening ") FET802 by activating negative raceway groove (N-ch) FET804, negative raceway groove (N-ch) FET804 self be the grid that is present in it with being connected of source electrode between the high voltage activation of abundance, this will reach 2.5 volts.Provide FET804 with the Vgs voltage transition on the grid of FET802 be logical circuit can use with control output stage low voltage.Directly open it by the logic-level voltages in the gate-to-source connection of N-ch FET806.
In the operation, provide the example that optical fiber 300 is encouraged, wherein optical fiber 300 is in discharge condition.It mainly is capacitive impedance that optical fiber 300 in the optical fiber layer 604 has.For the single piezoelectric element that drives with 60V to 200V, electric capacity is greatly about being between the 60nF to 200nF.For multilayer piezoelectric element, electric capacity can have lower driving voltage greatly about between the 1uF to 5uF, and it is so low to be about 10V.In the operation, can make optical fiber 300 ground connection by in the institute of equipment 10 unlatchings is free, activating FET806, yet ground connection can be provided all the time.Keeping the advantage that FET806 is in state of activation when optical fiber 300 discharge is, optical fiber 300 itself is in a known state (for example, it is " loosening " in known state, that is, do not extend or shrink).Can be by the Vgs driven at the grid place of FET804 be set to close to low-voltage state FET802.
For launching fiber 300, be that logic low voltage signals is closed FET806 by the grid that drives FET804, this logic low signal is provided by the low voltage drive circuit 808 that a set of pulses is provided under predetermined space or situation.Can use circuit as known in the art to come the operation and the element of design circuit 808.For example, can produce pulse by the pulse-width modulation circuit in the circuit 808.
In case with the gate driving of FET806 is low, the voltage at rail 814 places is offered optical fiber 300.The voltage at rail 814 places normally at about 10V (or lower) between the 200V (or more).Can provide (comprising charger circuit or the combination of the two) energy of rail 814 to supply with by energy storage device (for example battery or capacitor) or mobile electric power.Provide rail voltage to optical fiber 300 in, embodiment can adopt a kind of at least three kinds of circuit between optical fiber 300 and driving transistors 802 and 806.The first, series diode or resistance can be provided.In this configuration, circuit 808 is provided for controlling the charging of capacitance network of optical fiber 300 and the signal of discharge time.The second, a series resistance can be provided.When at the single charging and discharging pulse signal of 300 needs of optical fiber, can use this configuration.Value can together be used in some bimorph cells that need series resistance for the resistance of 5kohm to 10kohm.The 3rd, the combination of diode 816 and resistance 818 can be provided.If use single discharge and charging pulse, diode and transistorized combination allow the charging and the discharge rate that provide different.
Be back to the operation of circuit 800, close the delay that FET806 may need to add afterwards 50ns, thereby before FET804 output sensitizing pulse, make FET806 fully " closing ".After FET806 closes, be in logic high and FET804 is opened by the grid that drives FET804.After FET804 opens, the base voltage that the voltage that produces from the voltage divider that comprises resistance 810 and 812 is used to drive FET802 than the source voltage low about 5 of FET802 to 30V.Resistance 810 and the maximum Vgs of 812 restrictions come to abide by the rated value of FET802 and keep enough big so that suitable cut-in voltage to be provided of Vgs.Resistance 810 and 812 is big more, and just long more to the time of the gate capacitance charges of FET802, this has slowed down transistorized unlatching.In the PWM control system that provides for circuit 808, can use more low value to resistance 810 and 812.Circuit 808 can produce periodically, and activation signal comes to produce the predetermined period activation signal for optical fiber 300.For example, can provide the cycle pwm signal that optical fiber 300 is vibrated with the preset frequency of indication feedback signal.Alternatively, can imitate button to the pulse feedback signal that transducer provides PWM to create and click sound as feedback.

The typical principle of charging and discharge time is as follows.For charging, the charging cycle time that can notice about 300us can provide well clicks sensation.If the charging interval is long, then clicking sensation can be more " like rubber " and can not the relevant key zone of links active.If the slope is slow more, then more sensation, is noticed then that optical fiber 300 can be created more can listen to click and replace " clicking " if the slope is too fast like rubber, imitates clicking or relaxing of the plastic key that typically uses on electronic equipment.
For discharge, can provide feedback to imitate the sound of when the user discharges the button key of pressing on the electronic equipment, being heard of clicking.Yet, typically do not expect such feedback.Equally, can select discharge rate enough slow, yet also can sufficiently come soon to prepare for next charge cycle so that optical fiber 300 does not send the loud sound of clicking when moving back to initial position.Can notice to be about 3ms discharge time, and satisfy these parameters during more than 1ms.
